Earlier this year, Daniel was just another unemployed college student preparing for summer vacation.

"I was thinking of trying to get a job in video game design. I had been applying for internships -- and if that didn't work out, I was going to get an apartment with a friend and spend the whole summer coding," the 22-year-old forensics major told the Huffington Post.

But on a whim, just days before his summer holiday was due to begin, Daniel (who didn't want his full name revealed) said he came up with an idea that would change everything.

This summer, Daniel said, he was determined to do something dramatically different -- something meaningful and perhaps even a little profound.

I want to have a Reddit-powered epic summer adventure. As a result of having a family member employed by a large airline, I have the ability to travel non-rev status (if there’s empty seats and no one ahead of me in line), paying only departure taxes. I’d rather not disclose the specific airline, in case I get into shenanigans that might reflect on them.

Want me to hand deliver a letter to someone across the country or overseas? Attempt to help you with homework? Volunteer at your organization for a day? Need an extra pair of hands to do that landscaping project you’ve been putting off for months? Know a sweet hiking spot but have no one to go with?

"I realized that being able to fly for pretty cheap is a pretty big privilege, so I wanted to use it to the best of my abilities," he said. "Sure, I could've gone to Cancun or Ibiza and partied all summer, but I thought I'd be more productive and would really accomplish something if I helped people along the way."

Four countries and several US cities later, Daniel had accomplished around 30 to 40 things on his list.

Out of all of them, Daniel told the HuffPost that the one task that has impacted him the deepest was perhaps one of the most mundane.

"I washed a car for a family, which was a really simple thing to do. It seems like such a small thing, but it seemed to really help," he said. "Their son has down syndrome and leukemia -- and for me to do that one small thing and leave, they seemed pretty thrilled by it."

Daniel also said he was deeply moved by the outpouring of encouragement and trust showed to him by the many people he met during his travels.

"I was staying with complete strangers, through Reddit, and the generosity of these people I had never met just blew me away. From couches, floors, pull-out beds and home-cooked meals, there was no end to what people were willing to offer. Some people even offered to lend me their car -- which I thought was pretty crazy," he said.

Now back home, Daniel said he hopes that he'll be able to do this again sometime soon.

"If possible, I would love to do it next summer," he told HuffPost.
